To all whom t may concern.'

'lio it. known that l, JOHN ll. Musa, a citizen of the United States of America, residing at Cameron, in the county of Moore and State of North Carolina, have invented certain new and useful Improvements in Heating and Drying Apparatus, of which the following is a specification, reference being had therein to the accompanying drawinfr.

L'llhis invention relates to a heating and drying apparatus and has for its object the production of a simple and edicient means for distributing the heat equally throughout a barn or building within which tobacco is stored.

Another object of this invention is the production of a simple and efficient furnace which is so constructed as to radiate a maximum amount of heat from the heat energy collected therein.

With these and other objects in view, this invention consists in general of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

ln the drawings:

Figure l is a front elevation of the barn in which the furnace is placed.

Fig. 2 is a top plan view of the furnace.

Fig. 3 is a central longitudinal section of the barn, showing the furnace also in section.

Fig. 4 is a Fig. 3.

Fig. 5 is a section taken on-line 5-5, Fi

Fig.- 6 is a section taken on line 66, Fig.

Fig. 7 is a detail perspective view of a portion of one end of the furnace, showing the manner in which the inner and outer walls are locked together.

Fig. 8 is an enlarged vertical section through the bottom portions of the walls of the furnace, showing the manner of locking the same together.

lBy referring to the drawings it will be seen that 1 designates a barn or other housing within which is mounted a furnace for the purpose of throughly heating the interior of the barn and thereby thoroughly other material such as fruits and the like therein.

The furnace mounted within the barn 1 comprises an outer casing 2 and an inner section taken on line 1 4,

casing 3 whichv casings are arranged in spaced relation as shown clearly in Figs. 3, 7 and 8. The side walls of the inner casing 3 of the furnace are provided with laterallyextending flanges A and the side walls of the outer casing 2 are provided with laterally-extending flanges 5. rllhe danges 5 are adapted to fit Aor rest upon the flanges A, and these Hanges 4l are provided with upwardly-bent tongues 6, which upwardlybent tongues 6 are folded to overhang the flange 5 of the outer-'casing 2. Each flange 5 is likewise provided with a tongue 7 which is bent downwardly and folded around so as to extend under the dange i of the inner i casing. llt will, therefore, be seen that a very simple and efcient means has been produced for firmly and efficiently securing the inner and outer casings together and, at the same time, firmly holding these casings in proper spaced relation thereby permitting the free passage of air between the inner and outer casings.

As shown clearly in Fig. 3, a tank 8 may be placed upon the top of the inner casing 3 and this tank 8 extends through the outer casing 2 and is adapted to be filled with water forthe purpose "of efciently heating the water and transforming the same into steam, whereby the steam may be conveyed from the tank 8 through a steam-conveying pipe 9 to a suitable pack-house for casing the tobacco. lit, of course, should be linderstood that a suitable pack-house as indititl cated by the numeral 10 may be positioned v f at any suitable or convenient point with respect to the barn 1. lit further should be understood that the tank 8 and pack-house 10 may be eliminated from the system without departing from the spirit of the invention.

A plurality of radiating heat-distributing tubes 11 are secured to the sidewalls of the outer casing 2 and extend outwardly toward the sides of the barn 1, as shown clearly in Fig. 2 of the dra-wings. A plurality of heat-distributing or radiating tubes l2 are also carried by the rear end of the outer casing 2 for conveying heat toward the rear end of the barn 1.

For the `purpose of furnishing an additional heat-radiating surface and also a heat distributing means, a plurality of heat-distributing pipes in suitable numbers, indicated by the numeral 13, are extended longitudinally through the furnace and t snugly ico l against the inner face of the top of the inner casing 3 of the furnace, as shown clearly in Fig. 3 of the drawings. These heating tubes 13 have their forward ends passing through a front-plate 14 of the furnace and extend through the rear walls of both the inner and outer casings 2 and 3 of the furnace. It will, therefore, be seen that these pipes 13 will also constitute an elicient reinforcement for the top of the inner casing 3. As above stated, any suitable number of pipes 13 may be employed to suit the convenience of the operator or manufacturer.

A suitable burner 15 is-placed within the furnace, as shown in Fig. 3, and a burnerpan 16 is placed under the burner 15. A

' supply pipe 17 is connected to the burner 15 carrying an operating valve 18 and this supply pipe 17 leads to a suitable supply tank 19 mounted in any convenient or desirable point upon the barn 1.

A suitable door 20 is mounted in the front end of the inner casing 3 and carries a suitable slide gate 21 for the purpose of permitting the lighting of the burner 15 when so desired without the necessity of opening the entire door 20.

By carefully considering Fig. 1, as well as Fig. 3, it will be seen that the inner casing 3 is closed at its forward end and is spaced at its outer end from the outer casing 2 for the purpose of permitting fresh air to enter between the casings 2 and 3 and thereby at all times present a fresh supply of air to be heated by the burner 15. A suitable pipe 22 is carried by the furnace and communicates with the interior of the casing 3 and extends through the roof or any convenient part of the barn 1 for conveying gas fumes from the furnace.

As shown in Fig. 3, suitable trays 23 may be employed and supported in any suitable or desired manner within the barn 1.

It of course should be understood that any suitable or convenient fuel may be employed in connection with the present furnace without departing from the spirit of the invention, as it is not desired to limit or restrict the present invention to any specific form of heating means, such as a burner or the like.

It of course should be understood that other suitable mechanical changes may be( employed without departing from the spirit end of the building, said furnace provided with aninner casing and an outer casing, said outer casing provided with a plurality of horizontal heat-distributing tubes extending outwardly from the side walls thereof, a plurality of heat-distributing tubes extendin longitudinally the length of and throug'the rear end of said furnace and engaging the top of said inner easing and also constituting a brace for the top of said inner casing, means for conveying fumes from Said inner casing, and means for holding said casings in spaced relation to each other.

2. The combination with a building, of a furnace of the class described mounted in one end thereof, said furnace comprising an inner and an outer casing. said inner and outer casings being arranged in uniform spaced relation throughout the entire length and also being spaced with respect to each other at their outer ends contiguous to one end of said building for permitting the free entrance of fresh air at the outer end of said furnace between said inner and outer casings, means communicating with said inner casing for conveying fumes therefrom, horizontal heat-distributing tubes connected to the sides of said outer casing and extending outwardly therefrom toward the sides of said building, horizontal heatdistributing tubes connected to the rear end of said outer casing and extending toward the rear end of the building, and tubes placed at the top of the inside of said inner casing and extending its entire length and also extending through the rear ends of said inner and outer casings and being positioned at their rear ends contiguous to the rear end of the building.

3. The combination with a building, of a furnace of the class described positioned at one end of said building, said furnace comprising an inner and an outer casing spaced from each other, a tank extending through the top of the outer casing and resting upon the top of said inner casing, heat-distributing tubes extending the length of said inner casing and bearing against the inner face of the top thereof, said tubes extending through the rear ends of said inner and outer casings and having their rear ends positioned near the rear end of the building,`

and means for conveying fumes from the lnner casing to the outer atmosphere.

In testimony whereof I hereunto affix my signature.

JOHN BIRT MUSE.
